Who found Jupiters moons?
Galileo is the first person known to have seen the four largest moons of Jupiter. It took much better telescopes than Galileo's to see the myriad smaller bodies that orbit the largest planet. The current count of moons of Jupiter is 63, but there are certainly others too small to see using our current telescopes. And this doesn't count the smaller bodies which make up Jupiter's partial ring system.
What are jupiters 4 largets moons?
Jupiter's largest four moons, called the Galilean satellites because Galileo was the first person to see them, are Europa, Io, Callisto and Ganymede.
Why was Galileo able to see only Jupiter's largest moons?
Galileo was able to see only Jupiter's largest moons, Io, Europa, Ganymede, and Callisto, because these moons are the largest and brightest of Jupiter's many satellites. Their size and brightness made them visible using the relatively primitive telescope technology available to Galileo in the 17th century. Smaller moons may have been too faint to be seen with his telescopes.
What are two characteristics of telescopes that allowed Galileo to see so much in space?
reflecting and refracting telescopes
When Galileo looked at Jupiter with a telescope How many moons did he see?
He saw 4 moons
Galileo was the first person to see the moons of Uranus or Jupiter?
Galileo was the first person to observe the four largest moons of Jupiter, now known as the Galilean moons (Io, Europa, Ganymede, and Callisto), using a telescope in 1610. The moons of Uranus were discovered by Sir William Herschel in 1787, long after Galileo's observations.
How many moons did Galileo see?
The big one for the Earth, of course, which everybody sees. But Galileo was the first known person to see the four "galilean" moons of Jupiter; Europa, Callisto, Ganymede and Io. There are another 60 or so moons of Jupiter, but they are all much smaller; far too small to be seen in Galileo's early telescope!
Europa is a moon of what planet?
Europa is one of Jupiters moons. Jupiter has many moons, but Europa is one of the four large moons that was discovered in 1610 by Galileo Galilei (and possibly independently by Simon Marius around the same time).
What kind of data was collected by the mission Galileo?
The Galileo spacecraft collected information about Jupiter and it's moons ; see related link below .
First to see the four moons of Jupiter?
Galileo Galilei, when he trained his new telescope on the sky.
What 4 things did Galileo first see when he looked in a telescope?
Galileo looked at the planet Jupiter and observed its 4 largest moons (which are still known as the Galilean moons, to this day).
Which planet has the Galilean moons orbiting around it?
Jupiter. The "Galilean" moons are the four largest moons, which are so large that Galileo was able to see them orbiting Jupiter even with his relatively modest telescope.
